    We used single-strand conformation polymorphism (SSCP) to detect DNA polymorphisms in the 3' untranslated (3'UT) region of the gene for cystathionine beta-synthase (CBS). A polymorphism due to a T-to-C substitution at nucleotide 549 of the 3'UT region with heterozygosity of 46% has been identified. Genotypes for this polymorphism have been obtained in all of the informative CEPH families, and CBS has been placed in the linkage map of human chromosome 21.
